RAILWAY-TIE.

Application filed June 25, 1907.

Specication of Letters Patent.

To all 'whom t may concern:

Be it known that we, WILLIAM I. THOM- sON and SAMUEL G. THOMSON, residents of the city and county of Fhiladelphia, State of Pennsylvania, have invented an Improvement in Railway-Ties, of which the following` is a specification.

More particularly this improvement relates to a railway tie having more than one rail seat at either or both ends.

In the preferred form the ends of the tie are split or separated and bent apart to form two separate rail seats at each end. A tie thus constructed is narrower at the middle than under the rails, and this form affords the best resistance to endwise movement of the tie on the road-bed. Our invention is not, however, limited to this form, but may also be embodied in forms in which the central. portion of the tie is as wide or wider than the ends. In some cases also the separated rail seats may be employed at one end of the tie only, the other end having a single seat; and such lties may be arranged with the double rail seat at alternately opposite ends in successive ties.

'Ihe tie may be formed of a single piece having split or divided ends, but we prefer to construct it of structural metallic bars or pieces suitably fastened together and bent apart at the ends to form the separated rail seats.

The tie may consist wholly of metal, or wooden or other elastic elements may be introduced when desired.

One of the special advantages of a tie of this kind is that it permits a rail joint having a depending flange to be introduced between the separated rail rests of the tie at either end. It is also an advantage of the tie that a great increase in the footing, which may be provided to rest upon the ballast, may be obtained by introducing under the separated rests footings of metal, wood, or other substance,r extending across the space between the rail rests.

In the drawings: Figure 1 is a plan view of a tie embodying the invention in one of its forms; Figs. 2, 3, 4 and 5 are plan views of one end of the tie illustrating modifications; Fig. 6 is a plan view of a tie illustrating another form; Fig. 7 is a transverse section on the line A-A of Fig. 6 on an enlarged scale; Fig. 8 is a transverse section on the line B- B of Fig. l; and.Fig. 9 is a transverse section on the line GMG of Fig: 5.

a is the body of the tie which may consist of a single unitary piece or of separate pieces fastened together. The ends are split or bent apart to form separated rail seats as a a2 for the rails C. In our preferred form the tie is thus bent or slit at yboth ends to form such separated rail seats at each end; but in some cases these separated rail seats may be provided at one end only as in the form shown in Fig. 6.

The tie is preferably constructed of structural metallic members riveted or otherwise secured together to form a single tie structure, with the ends of the members bent apart to form the separated rail rests. In- -termediate spacing blocks g may be placed between the two members when required. In Figs. 5 and 9 we have shownv wedgeshaped blocks g placed between the members a a and clamps p p extending across the blocks at the top and bottom and embracing the flanges of the members a a and fastened to the blocks by spikes p2 or other suitable fastenings. This construction dispenses with the rivets for fastening the members t a together. We prefer to bend the eX- tremities of the members toward one another thus forming angular portions at the rail rests. This is particularly desirable where wooden blocks or members b are combined with the separated rail rests, either to form elastic rail bearings or fastening surfaces. In the forms shown in the drawings, these blocks are arranged so as to lie partly under the horizontal top flange of the metal members at the rail rests; these blocks may be fastened in any suitable manner. In the form shown in Fig. l. the vertical web of the metallic structural members is cut on each side of the rail rest and the ends are bent outward. to form a iiat surface as to which the block b is riveted; in Fig. 2 thev web is cut at the angle and bent inward, as at a4 at; the construction shown in Fig. 3 is similar to that of Fig. l but in addition a metal strap or yoke CZ is riveted to the web and embraces the block b; in the construction shown in Fig. 4 the web of the parts a a2 is cut out and the blocks are riveted to the yokes d d. which enables the blocks to extend to a substantial extent on the inner side of the rail rests a a2 and permits wider blocks or a single block under both seats to be used; in the construction shown in Fig. 5 the webs of the parts a a2 are severed and bent Ont to form arms 'as d5 which embrace the blocks and to which the blocks are riveted; and in the construction shown in the left hand of Fig. 6 the metal cleatsV other forms may be used, and we do not mean to limit our invention in this respect7 nor do we mean to limit ourselves to the use of the wooden blocks, as it is obvious that the rails may be secured directly to the separated rail rests a a2.

In the construction shown in Fig. 6 the separated or divided rail rests are used at one end of the tie only7 and,A while the other end of the tie is shown provided with the fastening blocks b b on'each side of the tie, such block may be used on one side only or the blocks may beentirely omitted. W'hen a tie of this form is used, it `is preferable that the ties should be alternately reversed in position. When the blocks b are used the 'rails may be secured to them by spikes 0 or in any other manner. p Y

In Figs. l and 8 we have illustrated the availability of our `tie for forming a rail joint between the divided railrests a a2.

The ends of the rails meet in the space be-l tween the rests a a2, and a rail joint L splices said rail. ends. The depending parts such as the flange 7a2 of such joint may extend down in the space between the rests. In Fig. 6 -a tie plate L is shown arranged in a similar manner.

When an increased footingv on the ballast is desired, it may be obtained by the introduction of a plate or sheett` under the divided members a a2 resting on the road-bed,

as shown in Figs. l, 6 and 7 As such plate or sheet spans the space between the members a a2 substantially the same footingv will be had, as there would be if the tie were continuous through the space between the divided members, and as this plate or sheet may be made of any area, it is apparent that such footing may be indefinitely extended. It is a special advantage of this construetion that it will prevent the tie becoming `g center-bound,' since it enables' the bearing on the road-bed at the center to be decreased while lpreservin-g anybearing surface that maybe desired at the ends under the rails. j

While we have shown the tie provided with only two separated rail rests at the end,V

more may be employed if desired.

Then we speak of the block or member I) as ay wooden member, it is to be understood that we mean to include a block or member composed of other suitable m-aterial or composition which may be used as a fasl tening member or elastic raill bearing.

What we claim is as follows:

, Al. A railway tie having two (side members rests at the same end of the tie. one of said members being bent toward the other member beneath the rail.

2. A railway tie compo-sed of side members tied together at their midlength and spaced apart by' a block at their extremities and diverging between said portions to their l points of greatest divergence beneath the rail to form independent rail rests.

3. A railway tie having two side membersextending from rail to rail, said members being spaced apart adjacent to one rail, and each having a separate block attached to it beneath the rail, one of said blocks having' a portion projecting inwardly beyondy an inside edge of the side member to which it is4 attached.

t. A railway tie having side members ex- .tending from rail to rail and forming two y separate rail rests at one end, said members converging at one end, and a separate wooden spiking block attached to each of said rail rests, the greatest distance between said side members being beneath the rail. y 5. A railway tie having a horizontally flanged integral member extending continu- ;ously from rail to Vrail and a plurality of j separate rail rests at one end, in combination j with a tie plate supported by said rail rests i and spanning the space between them.

6. A railway tie having a horizontally flanged member extending continuously f from rail to rail and a plurality of separate rail rests at one end, in combination with a footing plate extending under the bases of l-sald rests and spanning the space between them. v

7. A railway tie having twoseparate horizontally flanged members ateach end and a spiking block attached to one of said members, said block extending through and proi jecting to each side of said member.

j 8. A railway tie having a plurality of members extending continuously from rail to rail, and a rail fastening block extending.' through and projecting to both sides of onek of said membersl I 9. A railway tie having a plurality of members extendingk continuously from rail to rail and tied together at their extremities against an interposed spacing block, said members extending toward each other from a point beneath onerail to a point outside of the same rail.

g l0. A railway tie having a central body fwith a bifurcated horizontally flanged end f providing two separate and independent rail rests, the portions of saidv bifurcations lwhich lie outside of one rail extending toward each other from a poin-t beneath the same rail and being spaced apart by a block -lat their extremities.

ll. A railway tie consisting of a body lao having an end bilurcated, said bifurcations being horizontally flanged and bent beneath the rail at obtuse angles directed one toward the other to inclose a free space for stiii'ening flanges extending downwardly from a rail joint.

12. A railway tie consisting of a metallic body having an end bifurcated, said bifurcations being bent at obtuse angles directed one toward the other at the rail bearing portions, and fastening blocks secured to said bifurcations adjacent to said angles and extending laterally on the outer sides of said bifurcations.

13. A railway tie having a continuous member extending from rail to rail and a pair of separate rail rests at the same end of the tie, said pair of rail seats alfording greater width to the tie beneath the rail than at any other part of the tie which lies out from under either of the rails.

14. A railway tie having a continuous member extending fromv rail to rail and a plurality of separate rail rests at the same end in combination with a rail joint splicing two rails between said rests and having portions extending below the rail base into said space between the rests.

In testimony of which invention, we have hereunto set our hands.
